Bmrrnns, a citizen of the United States, residing: at Trlicksviiic, in His county of Luzernc zinii 5 State of Pennsylvania, have invented certain new and useful improvements in Compomni Adjustable Gear-Wheels, of which i-iik. following is a specification, reference it iing iimi to the accompanying drmvings.

This invention relates to r \viiceis S11(i1 as are used in spur gearing, and wiser gearing which is ipnrticuiziriy adapts} to use in prev .,.on mziciiincs iniiL in nniciiincs, gcnr cutting mzichincs, cic. 15 and pziri'icniziriy \\*il(1'(\ii.ii6 is :1 long train of goon.
